Take the finance sector: hard hit by losses during the financial meltdown, the richest seem to have bounced back and then some -â€" 155 of the sector's richest increased their fortunes by 20 percent in 2009.
To name a couple , Peter Hargreaves of Hargreaves Lansdown's wealth is up Â£260m this year and hedge fund manager Louis Bacon of Moore Capital increased his fortune by 69 percent to Â£1.1bn, making him the 49th richest person in the UK.
But elsewhere,many of the richest in the UK come from 'old' industries â€"- Lakshmi Mittal's steel empire earned him over Â£22bn, Anil Agarwal's Vedanta Resources mining business expanded by an some Â£3,500m, retailers Sir Philip Green and the Westons and (lower down the list) Matalan boss John Hargreaves, whose fortune trebled to over Â£1bn.
So it's left to the Reuben brothers' datacentre empire, Global Switch, to represent 'new' industry in the top 10.
Likewise, the fast-trackers among business people are largely in 'industry' -â€" the London-based Norwegian Odfjell sisters of Odfjell Drilling Group, property tycoon Joseph Lau, and a clutch of industry barons such as Leonard Blavatnik.
